1. The Maraton LV system Michela Lenzi INFN Firenze Thanks to V. Bocci, P. Ciambrone, A. Sciubba LV Power Supply RCM AC/DC converter

2. Michela LenziApr 6, 2006ECS Meeting The Maraton System Modular system made of three parts, the AC-DC converter, the control board (for monitoring and control of the LVPS) and the DC- DC modular power supply. Ethernet based - Remote controller unit separate from the power supply LV power supply Control and monitor board (RCM) AC-DC converter

3. Michela LenziApr 6, 2006ECS Meeting Status of Wiener OPC server  The Wiener OPC server is almost ready but not available before the hardware arrival (OPC server license included in the RCM order)  Sometimes there are wrong actual device readings for a handful of parameters (not critical)  “IT-CO provisionally approves the use of the Wiener Maraton OPC with the RCM / Maraton Crate combination – final approval being reserved until Wiener releases the complete OPC server” The OPC™ (OLE for Process Control) is a set of interfaces, based on OLE/COM and DCOM technology. The basic principle of OPC operation is that an OPC client (e.g. a SCADA) transfers data to/from PLCs/Devices by means of an OPC server. The OPC client can operate either locally (server on same PC) or via network, and the server accesses PLCs/Devices via drivers (e.g. drivers to fieldbuses and Ethernet based products).

4. Michela LenziApr 6, 2006ECS Meeting Main Maraton OPC items RCM:  Status (read): on/off  Settings (read/write): On/Off crate, On/Off groups CHANNELS:  Status (read): on/off, Failure Max temperature/current/ sense voltage/terminal voltage  Monitor (read): current, sense voltage, temperature  Settings & ReadBack (read/write): On/Off channel, Max current, max sense voltage, group number, Failure behaviour: ignore, switch off channel, group, crate

5. Michela LenziApr 6, 2006ECS Meeting Status of Maraton in JCOP The Maraton device has been integrated in the last version (2.3.6) of the JCOP framework: Device data structure OPC addresses Alarm definitions A set of common tools and libraries are provided to implement the Maraton specific control software  Facilities are available to set: “The JCOP framework is an integrated set of guidelines and software tools that include templates, standard elements and functions required to achieve a homogeneous Control System”

6. Michela LenziApr 6, 2006ECS Meeting Status of LV in ECS  I have implemented the first prototype of the control program for LV written in PVSS and integrated in the JCOP framework  Since the hardware and the OPC server are not yet available I have developed a Marathon simulator to test and debug the program  The program has been successfully tested at the SCADA lab. at CERN using the real OPC server connected to the real Marathon remote controller unit  Comment, suggestions,user requirements are welcome!

7. Michela LenziApr 6, 2006ECS Meeting program functionality  Create, copy, delete Marathon crate to control & monitor  Monitor crate and channels status (On/Off, Failure)  Monitor channel current, voltage and temperature  Setting parameters for each channel, group or crate  Switch on/off channels/groups/crate in a chosen sequence

11. Michela LenziApr 6, 2006ECS Meeting Conclusions  The OPC server is almost ready  A first prototype for ECS program is ready  The ECS program has been tested during developing with the JCOP driver simulator + a Maraton simulator I specifically implemented for this purpose  The ECS program has then been successfully tested with real OPC server and Maraton RCM (but no power supply!) in SCADA lab. at CERN (showing also that the simulator is reliable to test further developments )  I am waiting for the hardware to perform more accurate tests  Comments, suggestions and requirements on the functionalities needed for the commissioning are welcome!
